• 1/2 cup chicken broth

How to Make Cheesy Pierogi and Smoked Sausage Casserole

Step 1: Preheat the Oven

Preheat the oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray.

Step 2: Brown the Smoked Sausage

Heat the olive oil in a large skillet over medium-high heat.

Add the sliced smoked sausage and cook for about 4 to 5 minutes, turning occasionally, until the edges are browned.

Transfer the sausage to a plate and set aside.

Step 3: Cook the Onion and Garlic

Add the diced onion to the same skillet and cook for about 3 minutes, until softened.

Add the minced garlic and cook for another 30 seconds, just until fragrant.

Step 4: Prepare the Creamy Sauce

In a large bowl, combine the softened cream cheese, sour cream, whole milk, and chicken broth.

Whisk until mostly smooth.

Add the garlic powder, onion powder, smoked paprika, dried parsley, black pepper, and salt.

Stir in 1 cup of the shredded cheddar cheese.

Step 5: Arrange the Pierogies

Place the frozen pierogies in the prepared baking dish in an even layer.

You do not need to thaw or boil them first.

Step 6: Add the Sausage

Scatter the browned smoked sausage and cooked onions evenly between and over the pierogies.

Step 7: Add the Sauce

Pour the creamy sauce evenly over the pierogies and sausage.

Use a spoon or spatula to gently spread the sauce so most of the pierogies are lightly coated.

Step 8: Add the Cheese

Sprinkle the remaining 1 cup cheddar cheese and the mozzarella evenly over the top.

Step 9: Bake Covered

Cover the baking dish tightly with aluminum foil.

Bake for 25 minutes.

Step 10: Finish Uncovered

Carefully remove the foil and continue baking for another 15 to 20 minutes, or until the pierogies are tender, the sauce is bubbling, and the cheese is melted and lightly golden.

Step 11: Rest and Serve

Remove the casserole from the oven and let it rest for about 5 to 10 minutes.

Sprinkle with chopped fresh parsley if desired and serve warm.

Tips for the Best Pierogi Casserole

• Brown the sausage first: This adds deeper smoky flavor and better texture.
• Use frozen pierogies directly: There is no need to pre-boil them for this recipe.
• Soften the cream cheese: This helps the sauce combine more smoothly.
• Cover during the first part of baking: The trapped steam helps the frozen pierogies cook through.
• Uncover at the end: This allows the cheese to brown and the sauce to thicken slightly.
• Rest before serving: A few minutes of resting helps the sauce settle.

Frequently Asked Questions

Do I need to thaw the pierogies first?

No. Frozen pierogies can go directly into the baking dish. The covered portion of the baking time helps them become tender.

Can I use kielbasa?

Yes. Kielbasa is an excellent choice and gives the casserole a classic smoky flavor.

Can I use a different pierogi flavor?

Yes. Potato and cheddar, potato and onion, or loaded baked potato pierogies all work well.

Can I make this without cream cheese?

Yes. Replace it with an additional cup of sour cream and reduce the milk slightly, although the sauce will be a little less rich.

How do I know when the pierogies are done?

The pierogies should be hot and tender when pierced with a fork, and the filling should be heated through.

Can I add vegetables?

Yes. Broccoli, mushrooms, spinach, peas, or bell peppers are all good additions.

Can I use turkey smoked sausage?

Yes. Turkey smoked sausage works well and can make the dish slightly lighter while keeping the smoky flavor.
